WIRING INFORMATION:
1.
Each doubling of rated Watts increases sound output by 3 dBA. Field selectable input terminals are provided on each unit. The
following wattage selections are available: 1/8W, 1/4W, 1/2W, 1W, 2W, 4W, and 8W. Frequency range of speakers is 400-
4000Hz.
2. A
10
µ
F blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input.

1. Low Profile Speaker Strobe models have in-
out wiring terminals that accept two #12 to
#18 American Wire Gauge (AWG) wires at
each screw terminal. Strip leads 3/8 inches and
connect to screw terminals.
2. Break all in-out wire runs on supervised
circuits to assure integrity of circuit
supervision as shown in Figure 2. The polarity
shown in the wiring diagrams is for operation
of the appliances.
* Refer to Sync Module instruction sheets SM (P83123), DSM
(P83177) or Wheelock’s Power Supplies for additional information.
WARNING: THE SPEAKER STROBE APPLIANCES MUST BE FIELD SET TO THE DESIRED dBA SOUND OUTPUT LEVEL
BEFORE THEY ARE INSTALLED. THIS IS DONE BY PROPERLY INSERTING JUMPER PLUGS IN ACCORDANCE WITH THESE
INSTRUCTIONS. INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE, WHICH COULD RESULT IN
PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

Note: Use needle nose pliers to pull and properly insert the jumper plug to the desired tap setting.
Connect speaker wires to common and positive of terminal block and select the power tap terminal for 1/8W, 1/4W, 1/2W, 1W, 2W,
4W or 8W; 25V or 70V as required (see Figures 1, 2, 3, 4 and Table 4).
Each letter corresponds to a plug position of the header located on the printed circuit board. Select voltage and wattage as shown in
Table 4 below.

GROUNDING
:
Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.
WARNING: CHECK ELECTRICAL RATINGS SPECIFIED IN TABLE 1 AND 2 TO ENSURE PROPER ELECTRICAL INPUT. BE
SURE THAT SPEAKER WIRING IS CONNECTED TO SPEAKER TERMINALS ONLY AND STROBE WIRING IS CONNECTED TO
STROBE TERMINALS ONLY. CHECK TO INSURE THAT WIRING AT FACP IS CORRECT. IMPROPER ELECTRICAL INPUT
CAN DAMAGE THE PRODUCT OR CAUSE IT TO MALFUNCTION.
